HA Motorsports ECU jumper / conversion harness for installing a JDM OBD1 GSR (4-plug) automatic transmission ECU into OBD2A 1996-1998 Civic automatic transmission chassis. This harness is intended for use on the 96-98 Civic auto chassis when installing a GSR B18C1 engine along with B series auto transmission. Use this along with either the JDM GSR auto transmission or a USDM (OBD2A) 96-99 Acura Integra LS automatic transmission.
Uses all new OEM connectors for OE quality fitment. HA Motorsports ECU jumper harnesses are constructed using cross-linked automotive TXL wire that exceeds OEM specifications and is extremely durable.Important:
The OBD1 JDM GSR/P72 ECU is NOT able to be chipped/modified/etc. like the USDM P72 ECU's, therefore we recommend this setup only when using a stock or nearly stock B18C1 engine. If you will be modifying your engine, turbocharging, tuning, etc. we recommend our jumper harness setups that use a separate transmission control unit along with a separate chipped/tunable OBD1 ECU.
